I Specification of Letters Patent.

Patented May 11, 1915.

Application fled July 25, 1914. Serial No. 852,998.

To ail whom it may concern:

Be it known that 1, Joan F. OQonnon, a citizen of the United States,-res1dmg at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in -Ad ustabl e Side Bearings for Railway-Oars, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in adjustable side bearings for railway cars.

The object of the invention is to provide a side bearing for railway cars in which one of the bearing members is made adjustable to compensate for wear and varying conditions of service.

In the drawing forming a part of this specification, Figure 1 is an elevation of a body bolster and a truck bolster showing my improvements in connection therewith. Fig. 2 is an enlarged detail sectional view of one of the side bearings taken substantially on the line 2 --2 of Fig. 1. Fig. 3 is another detail sectional view taken on the line 33 of Fig. 2.

In the drawing, and referring to Figs. 1, 2 and 3, l0 denotes the body bolster and 11 the truck bolster of a railway car and which may be of any suitable construction. On each side of the king pin connecting the two bolsters, a side bearing is provided, as is customary, each of the side bearings, as shown in the drawing, comprising a lower member A secured to the truck bolster and an upper member B secured to the body bolster. The bearing member A comprises a base casting 12 riveted or otherwise suitably secured to the truck bolster, said base casting having pivotally mounted therein on trunnions 13, 13 a cradle 1 1 in which is rotatably mounted an antifriction roller 15.

The upper bearing member B which comprises the wear or striking plate or thrust member, is shown as comprising a hollow box-like casting 16 having laterally extend ing flanges at the top thereof 17 by which it is secured to the body bolster by rivets 18 or other suitable means. The casting 16 has end walls 19 and side walls 20, the end walls '19 each being provided with a horizontally bar 23, circular in crosssection, as shown, and prevented from accidental displacement by cotter pins 24. Mounted on the rod 23 s an ad usting member 25, which, as shown, is in the form of a prism having a dodecagon cross section and provided with end walls 26. The end walls 26 are perforated as indicated at 27 to receive the rod 23- therethrough, the holes or perforations 27 being eccentrically disposed relatively to. the axis of the prism. Mounted on and carried by the adjustable prism member 25, is a carrying bracket 28 having an upstanding cylindrical like portion 29 provided on the inner side thereof with a plurality of faces 30 corresponding in size and angular relation to the 12 faces 31 on the prism 25. At its lower end, the bracket 28 has a horizontally extending base 32 to the under side of which is secured a wear plate 33 by rivets 34:, the carrying bracket 28 having end strengthening flanges '35 as shown most clearly in Figs. 1 and 3.

With the parts as shown in Fig. 3, the wear plate is in its lowermost position but to ad1ust the same relatively to the roller beneath and the body bolster by which it is carried, the rod 23 will first be removed whereupon the bracket 28 and the prism 25 may be removed. Thereupon, the prism is withdrawn from one end of the bracket 28 and its angular position therewithin changed to the desired amount, thus bringments and yet the parts occupy. a relatively small space.

Although I have herein shown and described in detail what I now consider the preferred method of carrying out my invention, yet I am aware that numerous changes and modifications may be made in the details of construction and arrangements of the parts without departing from the spirit of the invention and all such changes and modifications are contemplated as-come within the scope of the claims appended hereto.

I claim: 1. In a side bearing for railway cars, a striking plate, and means for adjusting the height of said striking plate, said means ineluding an adjustable eccentric supporting member separable from the plate.

2. In a side bearing for railway cars, the combination with a casting adapted to be secured to a bolster, of a striking plate, and means for adjusting the striking plate relatively to said casting, said means including a supporting member separate from and ad justable to difierent angular positions relatively to said casting.

3. In a side bearing for railway cars, the combination with a bolster, of a se cured thereto, a thrust member, and an eccentric support for said member adjust able angularly about a horizontal axis, the

thrust member having a single bearing face.

4, Ina side bearing for railway cars, the combination with a casting ada ted to be secured to a bolster, said casting eing provided with bearings, an eccentric supporting member mounted in said bearings, and

a thrust member carried by said supportingmember, the thrust member and eccentric slipporting member being relatively adjusta le. a

5. In a side bearing for railway cars, the combination with a casting adapted to be secured to a bolster, of a thrust member, an adjustable support for said member, said support being a regular polygon in cross section.
